This study focuses on the fabrication and characterisation of single-walled carbon nanotube (SWCNT) buckypapers and polyethersulfone (PES) flat-sheet membranes using Cyrene, aiming toevaluate its efficacy as a green solvent for these applications. Pristine SWCNTs were dispersed inCyrene without surfactants and compared to N-Methyl-2-pyrrolidone (NMP) dispersions. Buckypapers were fabricated from these dispersions and characterised using Scanning ElectronMicroscopy (SEM), Atomic Force Microscopy (AFM), and infrared spectroscopy.

Cygnet-Cyrene blends could represent viable replacements for toxic polar aprotic solvents.

- Three new solvents, TBSA, EBSA, and MBSA, were developed to have high dipolarity and low toxicity, synthesized using a K60 silica catalyst in a solventless method.
- These solvents are notable for being water-immiscible and showed effectiveness in various chemical reactions, including a model Heck reaction and polymer solubility tests, matching the performance of traditional solvents.
- Toxicity assessments using in-silico models and in-vitro assays indicated that these new solvents do not present significant toxicity concerns, making them promising alternatives for industrial applications.
The bio-based mesoporous materials made from polysaccharides, Starbons® can be modified by two different routes to give high levels of N-content, unexpectedly including significant quantities of nitrile groups which can improve the materials performance in applications including metal capture.
